Hermetic Seal Test for Quality Control

There are Seal standard testing methods that are used to ensure the quality of products and equipment in all conditions. Hermetic seal testing is one such test that is carried out to improve the dependability of the equipment or product in question. It tests hermeticity, a lack of which may lead to failure of the equipment due to the presence of contaminants and moisture that would have entered due to an incomplete or improper seal. This testing is important for the proper working of space and military equipment, as well as devices used commercially.

There are many research and development companies that provide expert laboratory testing services to ensure quality control of products. When you want to get hermetic seal testing done on any of your product, make sure you look for lab testing services that provide Military Standard 883 method 1014 testing technique and Military Standard 750 method 1071 testing.

Helium spray sniff examination is done on packages with open cavity and also the ones that have undergone IVA testing. This test is carried out to identify leak site in packages. How devices are set up for the test is important to achieving best results. Vacuum is drawn to the leak detector from the internal cavity through either the leak site of IVA test or open cavity of the device. Helium spray has a tendency of making a helium patch in the vicinity of the leak site. As helium passes into the detector through the leak site, the location of the site can be detected. Kr85 testing can also be used to identify the leak site in packages. After Kr85 testing, the leak site can be identified by using an instrument to pass gamma rays through the device.
Another test that is used to identify leak sites is fluorescent dye impregnation. This testing is very helpful in not only knowing the regions of leaks but also in defining the physical properties of the openings. It is a method that enables improvement of processes used to seal packages.

If helium is used in sealing devices, krypton 85 or helium fine leak testing is done. In this process, a chamber with high pressure is used to precondition devices. On reaching optimum conditions, devices are checked for leak rate.
Our RFID seal is high security seal with different kinds of RFID chips. It is in order to offer improved traceability and easy retrieval of crucial information. RFID seal which we provide is RFID passive tag no need any battery support and It is wildly used as container seal for tracking or identification the container.
